Subject: Install charmaps uncompressed in testroot

The testroot does not have a gunzip command, so the charmap files
should not be installed gzipped else they cannot be used (and thus
tested).  With this patch, installing with INSTALL_UNCOMPRESSED=yes
installs uncompressed charmaps instead.

Note that we must purge the $(symbolic_link_list) as it contains
references to $(DESTDIR), which we change during the testroot
installation.

This is a good compromise between something we can use and something
we can't use for localedef testing (and I have a follow-on patch to
test localedef).

Please post v2 with new comments.

Needs a comment explaining why we use INSTALL_UNCOMPRESSED=yes, talk
about that compressed character maps can need gzip/bzip2 but that we
can't easily find target gzip/bzip2 binaries so to avoid this dependency
we install uncompressed character maps.

Needs a comment explaining what INSTALL_UNCOMPRESSED does.

Please expand comment to reference that this is being used by test-in-container
to install character maps without compression. This way anyone reviewing
this can immediately go find the testroot install code.
